A pair of scientists think we’ve over-counted the number of dinosaur species since we didn’t know enough about how they developed through life. (National Geographic) For example, scientists may have been counting infants, juveniles and adults of the same species as separate species since they seemed so different.
“Like birds and some other living animals, the juveniles went through dramatic physical changes during adulthood,” say paleontologists Mark Goodwin (University of California) and Jack Horner (Montana State University).
